J Airobject of thisinventio'n is to provide a f s'et or plurality of baking. pans, or so fcalled' multiple. baking pans, wherein the various desirablecharacteristicsand ieaturesj-oi, ad;

vantage now present 'in'variousltypes of multiple baking pans may be retained, and 1n whichthere maybealso attained certain other features that will obviate certain objectionable features in; "multiple baking pans as produced at this time, i l

"In'bak'ng pans it 's desirable to have absolutely smooth interior walls; whereforefl'the use of rivets and the like for' attaching bak ing" pans to suitablev supporting frames" is precluded. Accordingly, it is; necessary I to, provide somejpositiveiiixing means, otherthan'thejrivets, forattaching a row orplu ralityof preferably seamless individual pans to a, susta1ning,'f supportingeor attaching 20,

frame;v It has been common to, provide the individual pans with, flanges'along the free endsof 'h'e vpan and'to turn theseflang'es about the frame of the Y multiple pan; =One ofjthe difiiculties encountered in "this. type of construction has been "the fact that the sheet. metalfromwhich' th'eri'ndividual pans v are made, is'capable of but a limited amount of idrawing'; before the metalwill 'breaklfor. tear. Accordingly, the portions 'ofthe frame :Eormed,had to be s narrow that they gave about which such i drawn "flan es f could be inadequate support tof'amultiple pan structure, and. they "could notbe used as a spacing means between multiple ,pansIwhennestedsomeextentso that: they, WllljCQQli as qu ckly.

' I hese ,1 st ng. Plate en ba t n l workand expense and they arenot satisfactory because they are difficult to attach, and be cause an eii'ective attachment ofa nesting plate requires contact of a nesting plate with the pans at one or more places; It isnot "uncommon for uneven baking of the products to result from the unequal masses of metal dlsposedat'vari'ous places about the pan surface which causes unequal distribu tion of heat to theproduct being baked. An

object of this invention is, as previously;

stated, to attainthe'advantages of a smooth pan, thenesting feature, and rigidity of .mounting of the nesting means in a. simple 1 and econom cal manner without having-the resultant structure subject to the attendant disadvantages ofunequal masses of metal contacting the pans in such wise as would .efiect unequal baking of the parts of the product. i p

These and other objects are attained by the means described herein and disclosed in the accompanyingdrawings, in which:

' The individual pans 10 may be formed as they are commonly made and have flanges 11 formed along the upper extending walls. The flanges 11 are preferably made as long as possible withouttea-ring'or fracturing the metal." Although'three pans are shown as comprising the multiple pan structure, it is to be understood that 1 the number thereof may bevaried.

Aiframe 12 is provided and is o f such size that the requisite number of pans 10 may=be introduced into the frame. The framepref erably-comprises a single meta-lstrip ofconsiderablewidthythe upper end 15 of which is turned 101i bent,-for1providing the flange or vice versa.

{ the frame 12 and which" indicated atl3. The flange-13 is made of a width such that theflanges 11 formed on the walls of the pan may be turned around theflange 13 and may have their free ends 14; introduced into the channel 13 provided 'between the flangei 13 and the body 16 of theframestrap 12. The frame strap 12 is provided along its lower edge with a corrugation 17 which'setsfofl a flange 18 from the body 16 thereof. :[Th lower inner edge 19 of the flange 18 is adapted to contact upon the outer face 20 of the pan. The said-contact isprac tic'ally a line contact, wherefore there would be no such mass of material along thatline" contact as would have any eflectuponthe uniform and even baking of the bread. The;

' Y corrugation provided in the frame serves both tostrengthen' the frame and to give cer}- tain resiliency thereto as a result of which the frame functions'as a shock absorber for the multiple unit of pans. Thefr'ee ends. 1 1 of: the flanges'll formed on the pans, are clamped between the'flange-13. and the body lflby the die that't'urns' the flange 11 about also turns the ends 14 into, the channel 15, thereby providing a rigid mounting of the frame 12 upon the pans It should be notedthat the body 16-of the frame 12, because of the corrugations 17, recedes or diverges downwardly in relation to the pan wall'20, wherefore there is substantially no portion of the frame inysuch contact with the wall 20 of the pan f: as would in any way. affect the uniform bak; In ing of thesubstance within the, pan.

Instead 1 ofhaving a flange integral as is the flange 13,.a suitable bar 26 may be 'so positioned in relation to the body-22 and flange 23, that the flanges 11 on the pan, may be formed about the bar'26 andso'th'at the free ends 15 of the flanges 11 may beintroduced into the channel 27 between the body 22 and the bar 26. 'Thejframe 12 shownin' Fig. 4 and'its associated parts,cooperates with the pans in the same manner in which the frame 12 shown in Fig. 3 cooperates with the pans. I For all. practical purposes, the stripor strap 12 maybe considered as a continuous member, notwithstanding that in some in,

2.
